Description

Agastache rupestris FlowerKisser® ‘Silver Inferno’ (Hummingbird Mint) from High Country Gardens is a new cultivar of one of our favorite bestselling species. Agastache rupestris was introduced to the horticulture trade by David Salman in 1996, and it has since remained a favorite of High Country Gardeners. ‘Silver Inferno’ was initially selected by David Salman before his passing, and has been introduced under Lauren Carvalho as the Horticultural Manager of High Country Gardens.

Plants in the FlowerKisser® series are particularly nectar-rich and attract many pollinators, including honeybees, native bees, butterflies and hummingbirds. The name “flower-kisser” is the translation of “beja-flor,” the Portuguese word for hummingbird! ‘Silver Inferno’ was chosen for the FlowerKisser® series thanks to its striking blossoms, high nectar content, sturdy growth habit, and ease of cultivation.

Compared to the straight native species, ‘Silver Inferno’ has lighter silvery foliage and deeper flower colors, with nearly burgundy calyxes. In cultivation, it also shows greater resistance to powdery mildew. Similar to the classic A. rupestris, it is a magnet for hummingbirds, with a delectable, sweet, minty fragrance like root beer. The nectar-rich blooms are also attractive to bees, butterflies, and hummingbird moths. It will perform best in a dry, gravelly site. Cutting propagated.

Planting & Care

Tips for growing Agastache

Agastache are sun loving plants with aromatic foliage and flowers. They bloom from mid-summer into early fall and are resistant to rabbits and deer.

Agastache need lean, well-drained soils, prefer gravel mulches, and appreciate deep but infrequent watering after their second growing season

  1. Provide a fast draining soil that's naturally low in fertility, Don't plant into clay soils.
  2. Plant in full hot sun.
  3. Just a few handfuls of compost in the planting hole is enough. Don't plant into a rich, highly amended soil..
  4. Fertilize the Agastache just once in fall with Yum Yum Mix.
  5. New transplants need regular irrigation their first growing season to establish themselves. Watering can be reduced greatly during the second growing season when the plants have matured.

To improve winter-hardiness, and encourage re-seeding, leave the stems intact over the winter. In mid-spring, remove old stems just above the new foliage, about 4 or 5 inches above ground level.

If your conditions don't lend themselves to growing Agastache in your garden, they do well planted in containers.
